Outcome results
Percent Change From Baseline at Month 3 in Plasma VEGF Following Intravitreal (IVT) Injection of Anti-VEGF Agent
Percent change in blood VEGF level is calculated as the difference in blood VEGF level measured after 3 month of anti-VEGF agent IVT treatment (Ranibizumab or Aflibercept) when compared to baseline blood VEGF level.
Time frame: Change from baseline at Month 3
Population: Full Analysis Set (FAS): The FAS consisted of all randomized patients who received at least one dose of study treatment. FAS was the analysis set. However, patients who were randomized due to erroneous use of the IRT system and who did not receive at least one dose of study treatment were excluded from the FAS.
